Description
（One）Technical field
Heat recovery energy-saving technical field is the utility model is related to, more particularly to a kind of direct contact type spray heat reclamation device.
（Two）Background technology
Heat recovery is mainly used in the combustion more cleaned more by direct heat transfer and indirect heat exchange two ways, indirect heat exchange
On the fume treatment that gas boiler, oil burning boiler discharge, for the flue gas of discharged from coal-fired boiler, dust is more, after desulfurization
Flue gas, still containing more dust, and flue-gas temperature is less than dew point, the corruption of heat exchanging device after the corrosive elements condensation in flue gas
Corrosion is more serious.For indirect type heat exchanger because using more heat exchanger tube, dirt product, which easily occurs, influences heat exchange, while corrosion-vulnerable,
Cause maintenance of equipment high expensive.
（Three）The content of the invention
The utility model is in order to make up the deficiencies in the prior art, there is provided a kind of simple in construction, energy-conserving and environment-protective directly to connect
Touch sprays heat reclamation device.
The utility model is achieved by the following technical solution：
A kind of direct contact type sprays heat reclamation device, including lower section sets gas approach, top to set exhanst gas outlet
Main tower, it is characterised in that：The main tower bottom is provided with the bottom tank below gas approach, in main tower,
Internal spraying atomizing device, top dehydrating demisting device and mist eliminator flushing dress are disposed with above gas approach from bottom to top
Put.
Heat reclamation device of the present utility model is dehydrated by bottom tank, internal spraying atomizing device, top from bottom to top
Demister, mist eliminator flushing device composition, flue gas enters from side, top discharge, is exchanged heat with spray water mist counter current contacting, is
Integral structure pattern, during dirty cooling drops in flue gas, while realize the recovery of heat.
More excellent technical scheme of the present utility model is：
Resistant material is provided with the inwall of the main tower, strengthens the corrosion resistance of tower body, extends its service life.
The internal spraying atomizing device is made up of some spraying layers, and the quantity of spraying layer can be set according to flue gas tolerance,
To ensure fully heat exchange.
The top dehydrating demisting device is made up of coarse defogging device and smart demister, and coarse defogging device is arranged below, and essence is removed
Day with fog is arranged in top, and mist eliminator flushing device is arranged on the top of top dehydrating demisting device.
Manhole is provided with the bottom tank side wall, and side wall bottom is provided with spray water out, manhole
Position described in the utility model is not limited to spray water out.
It is provided with the side wall of main tower above the tank of bottom, the spout hole below gas approach, stores up bottom
Pond keeps certain liquid level, and normal level of liquid is in the lower section of gas approach.
The spraying layer of the internal spraying atomizing device and mist eliminator flushing device is located at king-tower by interior shelf
On internal wall.
The spray heat reclamation device that the utility model uses, recuperation of heat and place particular for the flue gas of discharged from coal-fired boiler
Manage and develop, and operating temperature range is wider, can preferably match the equipment that absorption heat pump etc. is applicable low-temperature space work,
There is unique advantage in flue gas heat recovery process field.
The utility model is simple in construction, easy to use, reasonable in design, effectively realizes the recuperation of heat to flue gas, drop is dirty, removes
The multi-effects such as dirt, energy-conservation, water saving, demisting, environmental protection and energy saving significant effect.
（Four）Brief description of the drawings
The utility model is further described below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure, 1 main tower, 2 manholes, 3 gas approach, 4 inside spraying atomizing devices, 5 top dehydrating demisting devices, 6
Mist eliminator flushing device, 7 exhanst gas outlets, 8 inside support, 9 spout holes, 10 bottom tanks, 11 spray water outs.
（Five）Embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.The embodiment includes lower section and sets gas approach 3, top to set
The main tower 1 of exhanst gas outlet 7 is put, the bottom of main tower 1 is provided with the bottom tank 10 positioned at the lower section of gas approach 3, main
Internal spraying atomizing device 4, the and of top dehydrating demisting device 5 are disposed with from bottom to top in tower body 1, above gas approach 3
Mist eliminator flushing device 6；Resistant material is provided with the inwall of the main tower 1；If the internal spraying atomizing device 4 by
Dry spraying layer composition；The top dehydrating demisting device 5 is made up of coarse defogging device and smart demister, and coarse defogging device is arranged in down
Side, smart demister are arranged in top, and mist eliminator flushing device 6 is arranged on the top of top dehydrating demisting device 5；The bottom storage
Manhole 2 is provided with the side wall of pond 10, and spray water out 11 is provided with side wall bottom；Set in the side wall of main tower 1
There is the spout hole 9 positioned at the top of bottom tank 10, the lower section of gas approach 3；The internal spraying atomizing device 4 and demister punching
The spraying layer of cleaning device 6 is erected on the inwall of main tower 1 by inside support 8.
